For whatever reason, there's a feeling that people seeking help on matters Linux are met with "arrogance". Typically, no example is given. I haven't yet encountered this arrogance (which does not mean that it doesn't exist or never existed in the past). I use the same username at wilders, askubuntu.com, and ubuntuforums.org. People are welcome to verify my claim for themselves. I even had just one question over at unix.stackexchange.com.
